Find The Top 5 Element For The Given Sorted Array In C#

Find the Top 5 Element for the given sorted array.

Solution 1:

public int[] ReturnTop5Element(int[] array1, int[] array2, int[] array3)
{
    int[] top5 = array1.Concat(array2).Concat(array3).OrderByDescending(i => i).Take(5).ToArray();
    return top5;
}

Solution 2:

private int[] Top5Element(int[] array1,int[] array2, int[] array3)
{
    int value=0;
    int  l1 = array1.Length-1;
    int l2 = array2.Length-1;
    int l3 = array3.Length-1;
    int[] Retarray=new int[5];
    for (int i=0;i<5;i++)
    {
        if ((array1[l1] > array2[l2]) && (array1[l1] > array3[l3]))
        {
            Retarray[i] = array1[l1];
            value = 1;
        }
        if ((array2[l2] > array1[l3]) && (array2[l2] > array1[l1]))
        {
            Retarray[i] = array2[l2];
            value = 2;
        }
        if ((array3[l3] > array2[l2]) && (array3[l3] > array1[l1]))
        {
            Retarray[i] = array3[l3];
            value = 3;
        }

        if (value == 1)
        { l1 = l1 - 1; }
        if (value == 2)
        { l2 = l2 - 1; }
        if (value == 3)
        { l3 = l3 - 1; }
    }
    return Retarray;
}
